Comunication rs 485

Postby florinraven » Mon Feb 28, 2011 2:53 pm

Hello, please help me with a problem
Fail to communicate through serial port 2 devices ( IOlog SS3018 and IOlog SS3188) both connected to a converter IOlog RS232 to RS485/RS422 converter SS3580.
Wish to use both simultaneously, one for reading the temperature and the other for interrupting a source...
Which may be the problem?
To be set when working with two modules, or more?
You should set a delay between the two?
Thanks,

You need to use the Modbus RTU driver for communication over RS-485. Define different addresses for the two modules. Define your devices to corespond with those addresses and then configure your gates.

It should work fine. I use other modules fron sielco but also on RS485 si a USB-RS485 converter.

Success!!
